SAFETY INSTRUCTIONS

1. Safety rules for USA

Safe operation practices for ride-on mowers

IMPORTANT!

This cutting machine is capable of amputating hands and feet and throwing objects. Failure to ob-

serve the following safety instructions could result in serious injury or death.

I. General operation

1. Read, understand and follow all instructions in

the manual and on the machine before start-

ing.

2. Only allow responsible adults, who are familiar

with the instructions, to operate the machine.

3. Clear the area of objects such as rocks, toys,

wire, etc., which could be picked up and

thrown by the blade.

4. Be sure the area is clear of other people

before mowing. Stop the machine if anyone

enters the area.

5. Never carry passengers.

6. Do not mow in reverse unless absolutely

necessary. Always look down and behind

before and while backing.

7. Be aware of the mower discharge direction

and do not point it at anyone. Do not operate

the mower without either the entire grass

catcher or the guard in place.

8. Slow down before turning.

9. Never leave a running machine unattended.

Always turn off blades, set parking brake, stop

engine and remove keys before dismounting.

10. Turn off blades when not mowing.

11. Stop engine before removing grass catcher or

unclogging chute.

12. Mow only in daylight or good artificial light.

13. Do not operate the machine while under the

influence of alcohol or drugs.

14. Watch for traffic when operating near or

crossing roadways.

15. Use extra care when loading or unloading the

machine into a trailer or truck.

II. Slope operation

Slopes are a major factor related to loss-of-control

and tip-over accidents, which can result in severe

injury or death.

All

slopes require extra caution. If

you cannot back up the slope or if you feel uneasy

on it, do not mow it.

Mow up and down slopes, not across.

Remove obstacles such as rocks, tree limbs,

etc.

Watch for holes, ruts or bumps. Uneven terrain

could overturn the machine.

Tall grass can

hide obstacles.

Use slow speed. Choose a low gear so that

you will not have to stop or shift while on the

slope.

Follow the manufacturer’s recommendations

for wheel weights or counterweights to improve

stability.

Use extra care with grass catchers or other

attachments. These can change the stability of

the machine.

Keep all movement on the slopes

slow

and

gradual.

Do not make sudden changes in

speed or direction.

Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and pro-

ceed slowly

straight

down the slope.

DO NOT

Do not turn on slopes unless necessary and

then, turn slowly and gradually downhill, if

possible.

Do not mow near drop-offs, ditches or

embandments. The mower could suddenly turn

over if a wheel is over the edge of a cliff or

ditch, or if an edge caves in.

Do not mow on wet grass. Reduced traction

could cause sliding.

Do not try to stabilize the machine by putting

your foot on the ground.

Do not use grass catcher on steep slopes.

III. Children

Tragic accidents can occur if the operator is not

alert to the presence of children. Children are often

attracted to the machine and the mowing activity.

Never

assume that children will remain where you

last saw them.

1. Keep children out of the mowing area and

under the watchful care of another responsible

adult.

2. Be alert and turn machine off if children enter

the area.

3. Before and when backing, look behind and

down

for small children.

4. Never carry children. They may fall off and be

seriously injured or interfere with safe machine

operation.

5. Never allow children to operate the machine.

6. Use extra care when approaching blind cor-

ners, shrubs, trees or other objects that may

obscure vision.

English – 3

SAFETY INSTRUCTIONS

IV. Service

1. Use extra care in handling gasoline and other

fuels. They are flammable and vapours are

explosive.

a) Use only an approved container.

b) Never remove gas cap or add fuel with the

engine running. Allow engine to cool before

refuelling. Do not smoke.

c) Never refuel the machine indoors.

d) Never store the machine or fuel container

inside where there is an open flame, such as

in a water heater.

2. Never run a machine inside a closed area.

3. Keep nuts and bolts, especially blade attach-

ment bolts, tight and keep equipment in good

condition.

4. Never tamper with safety devices. Check their

proper operation regularly.

5. Keep machine free of grass, leaves or other

debris build-up. Clean up oil or fuel spillage.

Allow machine to cool before storing.

6. Stop and inspect the equipment if you strike an

object. Repair, if necessary, before restarting.

7. Never make adjustments or repairs with the

engine running.

8. Grass catcher components are subject to wear,

damage and deterioration, which could expose

moving parts or allow objects to be thrown.

Frequently check components and replace with

manufacturer’s recommended parts, when

necessary.

9. Mower blades are sharp and can cut. Wrap the

blade(s) or wear gloves and use extra caution

when servicing them.

10. Check brake operation frequently. Adjust and

service as required.

• Watch out for traffic when working close to a

road, or crossing one.

• Be careful when rounding a fixed object so that

the blades do not hit it. Never drive intentionally

over a foreign object.

• The machine is heavy and can cause very

severe crush injuries. Be extra careful when

loading it on a trailer or truck.

• Be careful when pulling a load or using heavy

equipment.

a. Only use approved tow hooks.

b. Limit the load to what you can manage safely.

c. Do not make sharp turns. Be careful when

reversing.

d. Use counterweights or wheel weights when

indicated in the instructions.

Driving on slopes

Driving on slopes is one of the situations where

there is the most serious risk that the driver can

loose control or that the machine tips over, which

can cause severe injuries or be fatal. All slopes

require extra care. If you cannot reverse up the

slope or if you feel uncertain avoid cutting it.

Do as follows:

• Remove obstacles such as stones and branches

etc.

• Cut upwards and downwards, not sideways.

• Look out for and avoid driving over furrows,

holes or mounds. On uneven surfaces it is

easier for the machine to tip over. High grass

can conceal obstacles.

• Drive slowly. Select a low gear to avoid having

to stop and changing gear. It is also easier to

use the gear to brake in a low gear.

• Follow the manufacturer’s recommendations on

wheel weights or counterweights to increase

stability.

• Be extra careful with the grass collector or other

equipment which can alter the stability of the

machine.

• Always drive smoothly and slowly on slopes.

Avoid sudden changes of speed or direction.

• Avoid starting or stopping on a slope. If the tyres

begin to skid switch off the blades and drive

slowly down the slope.

not

do the following:

• Avoid unnecessary turns on slopes, and if

turning is necessary turn slowly and gradually,

downwards if possible.

SAFETY INSTRUCTIONS

Be extra careful when driving on slopes.

Cut slopes upwards and downwards, not sideways.

RIDER 850RIDER 850RIDER 850

English – 7

• Do not cut close to edges, ditches or banks. The

machine can suddenly tip over if a wheel goes

over the edge of a drop or a ditch, or if a bank

gives way.

• Do not cut wet grass. It is slippery and the tyres

can loose their grip so that the machine slides.

• Do not try to stabilise the machine by placing

one foot on the ground.

• The Rider lawn mower must never be driven

close to an edge or ditch when cleaning the

chassis.

Children

Tragic accidents can occur if the driver does not

pay attention to children in the vicinity. Children are

often attracted to the machine and the work of

mowing. Never assume that children stay where

you last saw them.

• Keep children away from the mowing area and

under the supervision of another adult.

• Be on your guard and switch off the machine if

children come into the work area.

• Before and during reversing look behind and

down for small children.

• Never allow children to ride on the machine.

They can fall off and become seriously injured or

obstruct an otherwise safe manoeuvre of the

machine.

• Never allow children to steer the machine.

• Be extra careful close to corners, bushes, trees

or other objects which obstruct your view.

Maintenance

• Petrol and petrol fumes are toxic and highly

inflammable. Be extra careful when handling

petrol.

• Store the fuel in containers approved for this

purpose.

• Never fill up the machine with petrol when the

engine is running. Let the engine cool before

filling up with petrol. Do not smoke, or fill up with

fuel in the vicinity of naked flames or sparks.

• Never fill up with fuel indoors.

• If leakage has occurred in the fuel system the

engine must not be started until this is rectified.

• Never store the machine or fuel containers

indoors if there are naked flames, such as in a

boiler room or where there is electrical equip-

ment which can emit sparks.

• Check the fuel level each time before using the

SAFETY INSTRUCTIONS

Keep children away from the mowing area.

Never allow children to drive the machine.

Never fill up with fuel indoors.

machine, and leave space for the fuel to expand

since the heat from the engine and hot sun can

cause the fuel to run over.

• Avoid overfilling. If petrol has been spilt on the

machine wipe it up and wait until it has evapor-

ated before starting the engine. If petrol is spilt

on clothes, change them.

• Be extra careful when handling battery acid.

Spilling acid on the skin can cause severe burn

injuries. Rinse immediately with water. If acid

gets into the eyes this can cause blindness.

Contact a doctor.

• Be careful with the maintenance of the battery.

Explosive gas is formed in the battery. Never

handle the battery when smoking or in the

vicinity of naked flames or sparks. Otherwise the

battery can explode and cause severe injuries.

• Never drive the machine in an enclosed space.

The exhaust fumes contain carbon monoxide,

an odourless, toxic and fatal gas.

• Make sure that bolts and nuts, especially attach-

ment bolts for the blade units are properly

tightened and that the equipment is in good

order.

• Never alter the safety devices. Check regularly

that they function. The machine must not be

driven with defective or unmounted safety

devices.

• Do not alter the setting of the governor and do

not race the engine.

• Reduce the fire risk. Keep the machine clean

from grass, leaves and other refuse which

fastens in it. Allow the machine to cool before

placing it in the storage area.

• Stop and inspect the equipment if you drive over

an object. If necessary repair the machine

before starting.

• Never make adjustments with the engine run-

ning.

• The parts on the grass collector can become

worn, damaged and aged, so that moving parts

are exposed or so that an object can be thrown

out. Check the parts regularly and if necessary

replace them with spare parts recommended by

the manufacturer.

• The machine is tested for safety and approved

only for equipment supplied or recommended by

the manufacturer.

• The blades are sharp and can cause cutting

injuries. Wrap over the blades or use protective

gloves when handling them.

• Check the functioning of the brakes regularly.

Adjust and maintain them as necessary.

SAFETY INSTRUCTIONS

Never smoke in the vicinity of the battery or the fuel.

Never drive the machine in an enclosed space.

Clean the machine regularly from grass, leaves and

other waste.

DRIVING

14 – English

5. When the engine starts release the ignition key

immediately back to neutral position.

IMPORTANT INFORMATION

Do not run the starter for more than about

5 seconds at a time. If the engine does not

start, wait about 10 seconds before trying

again.

6. Push the choke lever gradually forward when

the engine has started.

7. Set the required engine speed with the throttle

control.

DRIVING

WARNING!

Never run the engine indoors, in

enclosed or poorly ventilated areas.

The exhaust fumes contain toxic

carbon monoxide.

Driving the machine

1. Release the parking brake by pressing the brake

pedal.

2. Carefully press down one of the pedals until the

required speed is obtained.

To drive forward press down pedal (1), or to

reverse pedal (2).

English – 15

3. Select the required cutting height (1–7) with the

cutting height lever.

4. Push in the lock button on the lift lever and lower

down the cutting unit.

Cutting tips

• Localise and mark stones and other fixed

objects to avoid collision.

• Start with a high cutting height and reduce down

until the required mowing results are obtained.

• The mowing results are best with a high engine

speed (fast rotating blades) and low driving

speed (slow moving machine). If the grass is not

too high and thick the driving speed can be

increased or the engine speed reduced without

noticeably affecting the mowing results.

• The best lawns are achieved if the grass is cut

often. Mowing becomes more uniform and the

grass cuttings become more evenly distributed

over the surface.

The total time consumption is not greater since it

is possible to select a higher driving speed

without inferior mowing results.

• Avoid mowing a wet lawn. The mowing results

are inferior since the wheels sink down into the

soft lawn.

• Hose down the cutting unit with water

underneath each time it is used. The cutting unit

should be raised into the service position when

cleaning.

Mowing pattern

DRIVING

WARNING!

Clear the lawn from stones and other

objects which can be thrown out by the
